Leukippus and Democritus, in the Greek antiquity.
The first widely recognized atomic theory was proposed by John Dalton in the early 19th century. Dalton's atomic theory suggested that all matter is made up of small, indivisible particles called atoms. This theory laid the foundation for modern chemistry.
Two scientists came up with The Cell Theory. It was in 1839, Matthias Schleidan and Theodor Schwann, two German Biologists came up with this theory.
The idea that the world is made up of atoms was proposed by the ancient Greek philosopher, Democritus, around 400 BC. He suggested that all matter is composed of tiny, indivisible particles called atoms that are constantly in motion. This atomic theory laid the foundation for modern chemistry.
The first European credited with the atomic theory of matter is John Dalton, an English chemist, and physicist. Dalton proposed his atomic theory in the early 19th century, stating that all matter is made up of tiny, indivisible particles called atoms.
The ancient Greek philosopher Democritus is generally credited with first proposing the idea of atoms as indivisible particles that make up all matter. His atomic theory posited that these atoms are in constant motion and combine in different ways to form all substances.

The concept of atoms, or particles that make up all of matter, is an ancient one. However, John Dalton came up with the first scientific atomic theory in the early 1800s.

The pre-modern idea of atomic theory was proposed by Greek thinkers like Democritus, Leucippus, and the Epicureans, which would have been at about 500 to 300 BC.
He came up with the theory.
Neils Bohr came up with the kinetic Theory of Matter, also known as: The Molecuar Theory of Matter, and The Bohr Model.
State which
J.T Wilson was the one who came up with the theory of plate tectonics. Harry Hess came up with the theory of sea-floor spreading. Alfred Wegener came up with the theory of continental drift and Arthur Holmes proposed a suitable mechanism for this to occur (mantle convection).
Of the two, electrons. (Protons had to form, perhaps from quarks, before the first atoms could form and the temperature had to be cool enough for protons and electrons to come together to form hydrogen.)
